DEVICE FOR FORNIINGKWIRE-FENCE CLIPS.

SPECIFICATION forming part of Letters Patent No. 627,914, dated June 27, 1899.

Application filed February l, 1899- Serial No. 704,148. (No model.)

To @ZZ whom it may concern: l

Be it known that I, DAVID FRANKFORD, a citizen of the United States, residing at Elkhart, in the county of Elkhart and State of Indiana, have invented certain new and useful Improvements in Machines for Forming Fence-Oli ps, of which the following is a speciiication, reference being had therein to the accompanying drawings.

The invention consists in the construction of a machine for forming fence-clips; and it consists in the com bination,arrangement, and construction of the parts, as hereinafter described, and more particularly pointed out in the claims.

In the drawings, Figure l is a vertical central longitudinal section through myimproved machine. Fig. 2 is a detail section showing the position of the parts with the staple vin position at the completion of the movement. Fig. 3 is a horizontal section on line with the wire-feeding aperture, showing the drawing and bending die in elevation. Fig. 4 is a partial vertical section online xx in Fig. 3. Fig. 5 is a perspective View of the clip which my machine is designed to make.

The machine comprises a bed or base A,

having upon opposite sides the standards B,

in which is journaled the lever C. Beneath the lever O is the drawing and bending die D. This die is pivoted upon the transverse pivot E, having rocking movement, and is held in the desired position for the drawing of the staple into its U shape by the springs ct b, arranged upon opposite sides of its fulcrum. At the rear end it is provided with a finger F, the object of which will be hereinafter explained.

The forming-die preferably extends substantially across the space between the two standards B. It is provided atits middle with a longitudinal slot or groove c and upon each side thereof with the lugs G, which have the hooks or shoulders d in line and slightly in advance of the feeding-in aperture c through one of the standards B.

The lever C is provided with a shearingplate t, adapted to pass over the aperture c, and is provided with a hook I, adapted to pass in theslot or groove c as the lever is turned about its pivot.

In forming a staple into the ordinary U shape the parts are moved into the position shown in full lines in Fig. 1. The wire is pushed th rough the aperture e until it strikes the standard upon the opposite side. The lever O now turns about its fulcrum and in its first movement the shear h cuts off that por,- tion of the wire which is between the standards and which is of proper length to form the completed staple. This blank drops upon the drawing-die and rests against the shoul* ders d. The continued movement of the 1ever C will cause the hook I to engage against l the middle portion of the blank and bend the blank against the edges of the lugs G, as plainly shown in Fig. 3. The blank is prevented from springing up by the overhanging shoulders i on the edges of the lugs G, which are of the construction shown in Fig. fl. The lugs G are separated a sufcient distance to determine the spread or width of the staple. As the lever continues its movement it is evident that the wire will be bent in substantially U shape by being drawn between the lugs G, the springs maintaining the forming-die in positive engagement with the lever during this movement. If it is only desired to make an ordinary staple, this is all that `is required in the machine and the staple will be delivered in its completed shape as soon as the lever passes a sufficient distance beyond the end of the forming-die; but in -my machine I desire to bend the staple so as to form a hooked staple, as shown in Fig. 5, and thisis/aceomplished by the following means: Upon each side of the hook I on the lever O the lever is formed with the bending-lugs 7s, as shown in Fig. 2, and in rear of these lugs is a recess l. (Shown in that figure.) As the lever ap- Apreaches the end of its movement, so far as IOO release it, so that it will hang down from the hook I, and the reverse movement of the 1ever will disengage it therefrom and drop it free of the machine. The use and application of the hook or bending-staple to fasten said wires upon fence-wires is well known and is no part of my present invention.

A machine thus constructed is exceedingly simple, is certain in its operation, and very rapid in performing its function, with little chance of wear and without any small parts or pieces which are liable to get out of order.

It is evident that if desired the blanks may be cut into the proper length by a separate machine.

What I claim as my invention is- 1. In a machine of the kind described, the combination with a forming-die, of spacinglugs thereon against the base portions of which the wire blank is adapted to rest, an actuating-lever of the iirst class fulcrumed above the die, and a finger or hook constituting the shorter lever-arm extending downward between the lugs, said linger being adapted upon the initial actuation of the lever to engage lthe blank below the lugs, and upon the final actuation of said lever to pass between the lugs and draw the blank therethrough, substantially as described.

2. In a machine of the kind described, the combination with a rocking forming-die, of spacing-lugs thereon, against which the blank is adapted to rest, an actuating-lever of the first class fulcrumed above lthe die, and a tinger or hook upon the shorter lever-arm constructed, upon the initial actuation of the 1evcr, to engage the blank below the lugs, and upon the final actuation of said lever, to draw the blank between the lugs.

3. In a machine of the kind described, the 4o combination of the supporting-frame, the lever having a hook at the end, the pivoted drawing-die, the lugs G thereon, the shoulders d on said lugs, the overhanging flanges i on the side of the lugs, the hook on the lever being adapted to draw the blank between the lugs and beneath the overhanging flanges thereon, substantially as described.

4. In a machine of the kind described, the combination of the base and standards, of 5o the lever journaled therein, the drawingr and bending die pivotally supported therein, the lugs G, the hook I on the lever adapted to draw the blank between the lugs, the bending-lugs r, on the lever, the upturnedend or flange K on the forming-die and means for actuating the forming-die and bending the staple around the forming-lugs, substan tially as described. i

In testimony whereof I affix my signature 6o in presence of two witnesses.

DAVID FRANKFORD.
